摘要
以某国产型号飞机垂直尾翼50%的缩比模型为研究对象,采用压电陶瓷PZT和压电纤维复合材料MFC作为驱动器,对飞机尾翼的振动进行主动控制,该文主要采用时间序列法对该模型的控制系统进行系统辨识研究。首先选用最小二乘方法建立了系统的受控自回归模型(ARX)模型;然后通过实验获得了系统控制通道的模型;最后通过与其他方法进行比较和验证,表明了所用方法的可靠性和有效性。
In this paper, 50% aircraft vertical wing model is selected as the research object. PZT and MFC actuators are selected to control the vibration of the wing. A time series modeling method was employed to identify the control system. First, least square identification method is used to identify ARX model of the system. Then, the control channel model is obtained through the experiments. Finally, another system identification method is compared with the method used in this paper. Effectiveness and reliability of the method are verified.
